Lunar bone cyst filler is mostly known as lunar bone cyst lesion scraping plus bone grafting. Bone cyst is a benign lesion of the bone, and the surgery usually has no obvious sequelae, but there may be recurrence, peripheral soft tissue damage, and prosthesis rejection reaction after the surgery.

Peripheral soft tissue damage, if the bone cyst is large and involves more surrounding tissues, in cleaning the cyst may lead to damage of peripheral blood vessels, nerves, tendons, etc., and cause related symptoms. Prosthesis rejection, for patients who choose artificial prosthesis filler, there is a certain possibility of immune rejection of the prosthesis. Carrying out bone cyst lesion scraping plus bone grafting has a certain possibility of sequelae, but it is not difficult to deal with, it is recommended that patients under the guidance of the doctor, choose the appropriate treatment program.
